High power-handling, high-output ACOUSTIMASS® enclosures that deliver pure, rich bass in a variety of professional system configurations and for many different applications.
| Your business need: | The BOSE® Solution: |
| Full, natural sound without sacrificing space or aesthetics. | Patented ACOUSTIMASS® speaker technology delivers bass with no audible distortion. This makes it hard to locate the sound source, allowing you to conveniently place the ACOUSTIMASS® enclosure almost anywhere in the listening area, even out of sight. |
| Bass reinforcement for a variety of system components and configurations. | The 502®B ACOUSTIMASS® enclosure is engineered to complement the BOSE® PANARAY® family of loudspeakers with the exception of PANARAY® LT, for which the 502®BEX has been specifically designed. The PANARAY® digital controller or plug-in equalisation cards provide proper signal processing to ensure full, natural sound for any system configuration. |
| Bass reinforcement in large venues even outdoor. | BOSE® 502® BEX is designed primarily for use with BOSE® PANARAY® LT systems but can also be used outdoors to complement other loudspeakers in the PANARAY® range. |
| High output with reliable performance | A 30.5 cm (12”) woofer and a high temperature voice coil combine for high power handling, room-filling bass and dependable performance – performance that is backed by a transferable five-year limited warranty. |

Extensive research has yielded new technology in array design which, using a proprietary arrangement of Bose 4.5-inch full-range drivers, results in tightly controlled horizontal and vertical beamwidth, and extremely smooth band-to-band directivity. The system also features a new, compact low-frequency enclosure using Bose-patented Acoustimass technology. The Panaray 502 system is a highly aesthetic voice or music sound reinforcement system for permanent audio installations in theaters, auditoriums, churches, nightclubs, transportation facilities, and other places where people gather to be entertained, enlightened, or informed.
The 502 B Acoustimass enclosure uses a single high-power-handling, high-reliability 12" (30 cm) woofer. This new Bose-designed low frequency transducer features a high temperature, 4" (10.2 cm) voice coil,cast aluminum basket, and a highdurability rubber surround. The 502 B speaker provides clear, deep bass reinforcement from a small enclosure, using patented Bose Acoustimass speaker technology. Its low cross over frequency results in a non-localizable sound source, which allows it to be unobtrusively installed apart from the 502 A arrays. The enclosure is fitted with 10x safety-rated attachment points (top and bottom) for mounting in a variety of orientations.
Two-point suspension is easy to accomplish using the Bose CSB-5B suspension bracket. The 502 B is available in both Professional Gray and Arctic White, and is covered with a scratch-resistant vinyl, which can be painted to match any décor. The Panaray system digital controller is a single rack-space device which provides crossover functions, active electronic equalization, and dual-channel signal processing for both the 502 A and 502 B.
The Panaray 502 system includes a complete line of accessories for suspending or mounting both the 502 A and 502 B in a wide variety of configurations.

Engineers’ and Architects’ Specifications:
The low-frequency device shall be a dual-ported highly compact enclosure with matched active equalization as follows: The transducer complement shall consist of one high-power-handling driver of 30 cm diameter, mounted inside an enclosure such that distortion is minimized as a result of acoustic filtering. Its operating frequency range shall be below 150Hz so that non localizability shall allow a high degree of location placement flexibility. The input connector, located on the rear of the enclosure, shall be a screwtype barrier strip.
The enclosure shall be made of high strength, high-density resin-impregnated vinyl-wrapped particle board, with outer dimensions of 31.0"H x 14.0"W x 15.5"D (78.7 cm H x 35.6 cm W x 39.4 cm D); its weight shall be 85 lb (38.6 kg). The bass enclosure’s maximum acoustic output shall be 115dB-SPL from 55Hz to 150Hz, with measurements referenced to a full-bandwidth pink-noise input at 1 meter at the enclosure’s rated power. Its powerhandling capacity shall be 450W continuous referenced to IEC noise for 100 hours. The bass enclosure shall be the Bose Panaray 502 B Acoustimass enclosure.
